Embodiment

[0022] As shown in Figure 1, the naked-eye visible liquid crystal door grating stereoscopic image display device includes a PC host 1, a dual-screen card is arranged in the PC host 1, an image screen 2, and a grating screen 3 is arranged in front of the image screen 2, and the image screen 2 and the raster screen 3 are respectively connected with the dual-screen card; the dual-screen card is a general-purpose computer graphics processing card, which can synchronously display two frames of graphics on the raster screen and the image screen.

[0023] The working process of the naked-eye visible liquid crystal grating stereoscopic image display device is:

[0024] (1) Obtain the 3D model data of the stereoscopic image through a 3D object scanning instrument or artificial design, and input it into the dual-screen card in the PC host. Three-dimensional object scanning instruments include laser three-dimensional object scanners, medical equipment X-CT, RMI, B ultrasonic instruments,...

Abstract

The invention discloses a naked eye LCS stereopicture display device, which pertains to autostereoscopic imaging display technical field. The naked eye LCS stereopicture display device includes a PC, an image screen, a double screen card equipped inside the PC and a LCD shutter raster screen equipped in front of the image screen. The image screen and a filter screen are connected with the double screen card respectively. By the invention, people can watch stereopicture without wearing special glasses or helmet and can move freely from different directions to watch different facades of the stereopicture, with no eyestrain. The invention also can be applied in advertisement and entertainment place, as well as stereotelevision and also can be applied in science research, medical observation, engineering exploration and other fields.

Description

technical field [0001] The invention relates to the technical field of autostereoscopic imaging display (Autostereoscopic Displas), in particular to a naked-eye visible liquid crystal grating stereoscopic image display device. Background technique [0002] There are many methods and principles of stereoscopic imaging. For example, people use two cameras to imitate people's left and right eyes to shoot movies at the same scene, and then show the two movies synchronously on the same screen. The audience only needs to wear special polarized glasses , you can see a three-dimensional movie; on the monitor of the TV or computer, let the odd-numbered frames of the electronic scanning line display the left-eye image, and the even-numbered frames display the right-eye image. Open synchronously with the odd-numbered frames, let the right eye lens open synchronously with the even-numbered frames to see the stereoscopic image; there is also a kind of helmet-like glasses for the viewer, ...
